[TD=“class: alt1, bgcolor: #FFFFFF”]Hi guys,  
I’m trying to make a simple test for my current project and I have som problems with Vector class. I’m assigning BitmapData to the MovieClip and store this MovieClip to an Array. Then I’m able to access BitmapData.

If I do the same but use Vector instead of Array class, I get this error if I want to access BitmapData:  
1119: Access of possibly undefined property bitmapData through a reference with static type flash.displayDisplayObject.

What am I doing wrong? Thanks for your answers.
